For now there is no such policy

5. like omniORB, have a time-out and garbage-collect no longer used
6. ensure your clients close the connections when they no longer use it
It looks like your client just spawns, sends a requests, then no
longer interact, so you may
do a proper clean up of the system by calling CORBA.ORB.Shutdown
Note it is perfectly valid to call CORBA.ORB.Shutdown even if your
to do some other computations. but I need to understand a bit more
your client lifecycle.
